History and Future of Rare Earth Elements

The Future of Rare Earth Elements. Rare earth elements are likely to remain an important part of our future—from quantum computing and material sciences, to medical applications and advances in green technology. They are essential in efforts to reduce greenhouse-gas emissions enough to avoid the most devastating consequences of climate collapse.

Mining Rare Earth Elements, the Environment, Tech, and the

Mar 28, 2020The process of mining REEs is ecologically devastating. Processing one ton of rare earth metals releases 2,000 tons of radioactive materials, carcinogens, toxic compounds, acids, and other pollutants into the environment. Since thorium and uranium often occur alongside REEs in nature, tailings from mines tend to be radioactive.
